Only difference is the head of the filter. Hope this helps. **Q: will it fit HW-303B?** A: Not well. They are slightly too large for the 303.

It has gotten partially clogged lately. My fish tank water became stink and cloudy. I could hardly see my fishes. Received the pads today and installed right away. About 4 hours later, the fish tank water became sparkling clear and not stink any more. The performance of these perfectly fit pads is way beyond my expectation. I thought it would take days at least. The price is quite reasonable too. I am glad I bought these pads instead of a new canister filter. Will recommend to anyone without hesitation. ### ⭐⭐⭐⭐⭐ SunSun replacement sponges *by on Reviewed in Australia 16 October 2023* The sponges fit perfectly into my filter and they are three different degrees of coarseness, Very happy with my purchase. Would recommend. ## Frequently Bought Together - AQUANEAT 9 pcs Replacement Aquarium Canister Filter Pads Compatible with SUNSUN HW-304B/404B/704B/3000 CF500 Filter Pads Bio Sponges - AQUANEAT Replacement Canister Filter Pads Compatible with SUNSUN HW-304B/404B/704B/3000 CF500 Aquarium Filter Media Generic Floss - Marine Color 9w Lamp Bulb, Spare Bulb for Sunsun Hw-303b 304b 404b Jup-01 Filter Cf400, Cf500, G23 2 Pin, --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/499574103-9-pcs-compatible-aquarium-canister-filter-pads-for-sunsun-grech](https://www.desertcart.kg/products/499574103-9-pcs-compatible-aquarium-canister-filter-pads-for-sunsun-grech) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-09-28*
